The HD 5870 already measures in at an unheard of 11″ long, bigger than what a lot of case manufacturer’s have budgeted for (standard spacing is 10.5″). Images obtained this morning seem to depict that the x2 version could be even bigger!

While it is difficult to get an accurate length just from pictures, with a second die , it would be nearly impossible to squeeze it into the same sized PCB as the 5870. From our basic visual calculations, the card appears to be extended by at least 1″ – 1.5″, giving it a total footprint of an estimated 12″-12.5 inches long. Best of luck fitting this behemoth into any mid sized tower, or even a smaller full tower.
